About the Central Image

Our central image depicts an ever-growing cone, or cornucopia, which
expands not only in size, but in dimension.

The 0-dimensional portion of the image consists of points displayed
along a curve spiraling out from a center.

As we reach the 1-d position, the curve itself comes into view as a
1-dimensional curve.

Beginning at the 2-d position, the curve becomes the image of a
2-dimensional strip, which becomes wider and wider.

When it reaches the 3-d postion, the strip is replaced by a conical
shell, with circular cross-sections centered on the curve. But mathematics
does not stop there.

At the 4-d position, the figure should become a 4-dimensional object,
with spherical cross-sections centered on the continuation of the curve.
Such an image is difficult to portray on a flat poster, but it can be
represented, at least partially, by computer simulation.
